## Abstract Two published procedures for glass capillary column production are applied to produce capillaries for chromatography of polar natural compounds. Soda lime glass capillaries, after leaching with aqueous HCL, are either treated with colloidal silicic acid or with barium carbonate and coat

## Abstract As an alternative to acid pretreated UCON and FFAP capillaries for the analysis of wideโboiling free fatty acid mixtures, OVโ1 : FFAP phase mixtures were used on highโtemperature silylated inert glass capillary columns. The HETPโcarrier gas velocity curves, peak asymmetry factors, coati
For the preparation of capillary columns by the static coating method [I] considerable volumes of solution containing the liquid phase in a concentration range of 0.05-2.0% are used. For convenience and economy we have for many years prepared such solutions in batches of 50-100 ml, and have continue
## Abstract The development of improved high resolulation glass capillary columns for separating the alditol acetates of neutral and amino sugars is described. Different capillary column treatments were evaluated for their activity toward amino sugar derivatives and for their effect on the efficien
